I love this thread because this applies to most of the names I love. I also want to clarify that I wouldn't be naming my children after any of these people/characters, they are just the reason I first heard or fell in love with the names.

Edmund- my grade 3 teacher read us The Lion, The Witch and the Wardrobe and that was when I fell in love with Edmund. Catharine- I did a project on CatharineParrTraill in grade 12 Canadian history, and that's what solidified my preference with the spelling... though I'm not sure if she counts as a celebrity.Cedric- HarryPotter, I can't lie. Clara- HeidiEphraim- I first heard this on the WB show Everwood. They spelled it differently, but I love the name!Evgeni- EvgeniMalkin, hahaha. I don't even like Pittsburgh, but Evgeni is an awesome name.Ezra- uh, Tayor Hanson's kid made me take note of it.
Gaël- Gael García BernalHortensia- I read a book by Hortense Powdermaker in 4th year and I took note of Hortensia because of it. While combing this Valencian names document I have, Hortènsia came up, and it sparked my interest.Hyacinth- the character on "Keeping Up Appearances" hahahaIker- noticed because of Iker Casillas, kept on the list because I'm in love with the Basque Country. Leonor- the Infanta of Spain. I don't care about the royal family but I do love this name!Marius- I read a play in grade 10 French called "Fanny", and Marius really stuck out to me, especially in French. Love it!Moira- WendyMoiraAngela Darling. PeterPan is by far my favourite story ever.Paget- I have a bit of a girl crush on PagetBrewster, lol.
Pastora- there's this flamenco singer named Pastora Pavón (La niña de los peines)Rafael- Rafael Nadal, not gonna lie. Romola- I went through a Dirty Dancing: Havana Nights phase a few years ago and the lead actress' name is Romola, I thought it was pretty. Rosaline- pretty much the only thing I like about Romeo and Juliet.Viola- I loooove Twelfth Night!
